First step : make the mobidai.
(do not hesitate to ask me the original file, the picture is not real size).
Print the disc (5” diameter – 13 cm) and glue it on a plain cardboard (0.08” thickness – 2 mm).
Hollow out the center and cut on the 32 black lines. To enlarge, I slipped a ruler into cuts.
The upper right thread is moved below on the right (yellow on the right of green).
The lower left thread is moved up on the left (pink on the left of clear blue).
Turn your mobidai a quarter of tour towards the right (or towards the left if you are left handed. It’s as you want but always turn in the same direction).
Turn your mobidai a quarter of tour and make the moove.
With the hand which holds the mobidai, guide your kumihimo by bottom (keep it centered and pull slightly).
To make a bracelet I cut threads 22” (55 cm) long.
